Traces Of Gold In Tree Leaves Can Help Pinpoint Deposits — Australian Miner

(Kitco News) - After finding traces of gold in tree leaves, a South Australian miner says vegetation around gold mines can help pinpoint the exact location of the best gold deposits.

Marmota Energy has successfully spotted gold elements, such as manganese, in vegetation around the Aurora Tank gold mine site in South Australia.

By using biogeochemical sampling Marmota discovered that the roots of the Gum trees around the mine have soaked up microscopic gold particles in the areas with high-grade gold mineralization. The gold particles then travelled up the trunks of trees and towards the leaves, the company said in an ASX announcement.

“Biogeochemical exploration involves the sampling of plant matter (e.g. tree leaves at the surface) by chemical analysis, with the aim to identify mineralization below the surface,” the company wrote.

“Marmota is very pleased to announce that assay results from the December biogeochemical sampling have identified multiple new gold drill targets based on gold anomalism in tree leaves … The program has also identified zones that are anomalous in elements such as Antimony and Bismuth that are widely considered to be significant pathfinders for gold,” the statement added.

Marmota analyzed assay results from 329 leaf samples, revealing multiple gold drill targets and "pathfinder" elements associated with presence of gold, including antimony and bismuth.

“Analysis of the results highlights elevated anomalous gold (Au) distribution in plants sampled over and immediately adjacent to known mineralization at Goshawk,” Marmota said. “Gold can exhibit a nugget effect with respect to plant assays (as with other sample media) and have a limited anomaly footprint. For these reasons, a combination of gold and pathfinder elements is likely to represent a highly effective tool for [gold] exploration at Aurora Tank.”

The miner has carried out this research program back in December 2018. But this kind of testing is not new and stems from other work completed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australian Mining reported.
